Iraqi police and health officials say a mother and three children have been stabbed to death in their house in eastern Baghdad.
A police officer says the four were found Monday morning in their house in the mainly Shiite area of Kamaliyah. The children ranged in age from four to 10 years old.
The motive behind the killings was unknown and police are investigating the murder.
A health official at a nearby morgue confirmed the incident. The officials spoke on condition of anonymity as they were not authorized to release information.
